To all whom, it may concern:

Be it known that LVVIJLLIN G'lON R. HoYLn, a citizen of the United States, residing in Bay, in the county of Williams and State of North Dakota, have invented certain new and useful Improvements in Railway Appliances, of which the following is a description, reference being had to the accompanying drawings.

My invention relates to improvements in railway appliances, and particularly to means for raising the journal-box of a railway-car relatively to the car-axle in order to facilitate the removal of the br'asses when the latter have become worn or-for any other reason have to he removed. In performing this ops eration use has been heretofore made of what are calledchain-jacksf. but so far as is I known to me the chain after passing from the wheel-hook orrim-engaging device to under the journal-box is then wound around the arch-bars of the trucks and there fastened. The result is that a downward pull is exerted upon the Wheel and an equally great down-' ward pull is brought upon the arch-bars which carry the journal-box. The net result is that there is a crowding sidewise of the brasses as the chain is tightened by the movement of the wheel, and the ,brasses are pinched, so that it is impossible to; loosen them.

In my improved chaiikjack the car-frame is formed with a longitudinal sill aroundwhich the grab-hook enduof the chain. is wound. The arch-bars are thus relieved from the direct application of the pull and relative vertical movement between the m rial-box and, the brasses is permitted result ing in the inimediate loosening'of the presses tea degree which moval.

Another feature of my invention resides in the wheel-hook provided; This Wheel-hook is formed with two open ends or is of a form somewhat resembling the letter The chain-engaging end is rounded and pointed (or conical) in shape, while the rim-engaging end of the hook is shaped to firmly engage the wheel over the flange and in the circumpermi'ts of their ready re ferential depression inv the face of the wheel The portion of the hook between the chain-engagin f end and the wheelengagin end is practical y straight. The re sult of t 's. construction is to givethe wheelnear thereto.

"the wheel m carries t e wheel-hook hook a solid hearing across the rim of the wheel, a firm grip over the flange 'of the same, and a freedom of self-adjustment under the stress of the pull not obtained in the-wl1eelhooks heretofore used in these devices. Moreover, when the pull is released the ring on the end of the chain is readily disengaged from the pointed end of the wheel-hook and the latter is readily disengaged from the wheel is as readily:

top to bottom toward the front, and rojecting-rearwardly from the bottom of he hop,- per is a part I) of the longitudinal sillupon which the hopper is supported. The front art of the caris correspondingly constructed.

etween the vertical support or-hrace c, the sill t, and the hopperaisan open space d, through whichthe grab-end portion of the chain ernay he passed inzwinding it around the sill; The u fheelshook end of the chain is provided withs. ring-f, which is slipped over; I the conical end 9 of the wheel-hookh. The

wheel-engaging fend 't'Of the Wheel-hook fits. river the flange j and engages the face i'cof the wheel ,The portion at of the wheel-hook practically straight, and when the wheelhook is in position it extends over the rim 0 of the wheel." A. grab-hook p is provided at the other end of the chain, the'grab -hook engaging one of the links of the chain inv order tolock the chain in position around the sill.

- Theparts beingin the position shown'in Figs. 1 and 2, the car is moved slightly f r- Ward, and the conse uentf'orward rotation of upwardly, thereby tightening the chain and bringing an upward thrust to hear-upon the bottom of the journal-box g. The latter is thus moved upwardly relatively to the car-axle 1?, thereby loosening the brass s and permitting its ready removal. The chain is readily removed after the operation, since by a slight slackening the operator is enabled to slip the ring f over the conical end 9 of the wheel-hook, and

thereby to release the latter, after which the grab-hook p is readily disengaged from the link of the chain.

My new chain-jack is most efficient in operation, forcing the journal-box g, not downwardly, but vertically upward without the crowding sidewise of the brasses. The flangeengaging end of the wheel-hook has a firm grip on the wheel, so that slipping is impossible. The chain-engaging end of the hook it is readily engaged with and disengaged from the ring f. The whole construction is designed to make the device in operation very speedy andiefiective.

In some of the new forms of ore and coal cars the vertical sides of the car are supported upon posts or struts which rest upon the sill, the bottom of the car sloping inwardly from near the middle of the posts to form a hopper portion. Thus there is left open spaces between the posts, through which the chain may be passed in tying it to the sill. In many other of the ears open spaces w are left between the vertical side of the car and the'sill, where the vertical side of the ear rests, not upon posts, but springs directly from the sill itself.

What I claim is- 1. In a chain-jack, the combination of a chain provided with a fastening device at one of its ends; and a wheel-hook having its chain-engaging end bent oppositely from its wheel-engaging end and formed with a conical tip over which the other end of said chain may be readily slipped. to engage and disengage it therewith and therefrom; said wheelengaging end being formed with a hook constructed to fit over the flange of-a car-wheel and to engage one of the faces thereof; and the part of said wheel-hook between its said ends being practically straight and constructed to rest across the rim-face of a car-wheel.

2. The combination in a structure of the class described of a car provided with a hopper, a sill projecting beyond said hopper and trucks upon which said. hopper and sill are supported, said sill forming a means for the attachment of a chain; journal-boxes mounted. in said trucks; brasses mounted in said journal-boxes; a car-axle journaled in said brasses; a car-wheel mounted on said caraxle; a wheelhook which engages the flange of said car-wheel and is provided with abent conical chain-engaging end and a chain one end of which is fastened to said sill over its projecting end, the chain passing under the journal-box and having its free end attached to said wheel-hook by slipping said end over the conical chain-engaging end of said wheelhook.
